Abstract
The invention discloses a cable tightening device comprising a holding plate and pre-tightening members fixedly arranged on the holding plate, wherein there are no less than two pre-tightening members; and every two adjacent pre-tightening members are fixedly arranged on the upper end surface and the lower end surface of the holding plate respectively. Each pre-tightening member comprises an arc-shaped cover fixed to the holding plate, a pre-tightening telescoping rod and a pre-tightening spring, wherein the pre-tightening telescoping rod and the pre-tightening spring are arranged in the arc-shaped cover. The holding plate is provided with a through hole in the center of the orthographic projection position of the arc-shaped cover. The pre-tightening telescoping rod is installed in the through hole of the holding plate, with the two ends of the pre-tightening telescoping rod protruding out of the holding plate. The pre-tightening spring is sleeved on the pre-tightening telescoping rod and is arranged between an arc-shaped protrusion and the holding plate. The two sides of the arc-shaped cover are respectively provided with a guide through hole for a cable to stretch into and out. The holding plate is provided with a cable guide hole between the two pre-tightening members. According to the cable tightening device adopting the above technical scheme, the pre-tightening of the cable is completed through spring telescoping mechanisms in the two pre-tightening members, and meanwhile, the cable has a certain stretching stroke.
Description
Technical field
The present invention relates to cable tight directly installs.
Background technology
Existing common cable large span is set up all and is completed by high trestle, cable between two end supports can not be completely tight straight, need a reserved part, under the Action of Gravity Field of cable, cable can curve a radian downwards, when wind-engaging power effect teeter, swing inertia so very large, greatly affected the useful life of cable, simultaneously because cable center is downward, and then as the setting height(from bottom) that will reach cable must increase again the height of support, cost increases a lot, and then research and develop and a kind ofly can tightly directly can provide again the device of cable tensile strain performance to be very important in cable straight line.
Summary of the invention
The present invention is directed to above-mentioned technical problem, proposing a kind ofly can tightly directly can provide again the cable tight of cable tensile strain performance directly to install in cable straight line.
For reaching above object, be achieved through the following technical solutions:
Cable tight directly installs, and comprising: grip plate and be fixed on the preload piece in grip plate;
Preload piece quantity is no less than two, and does not have two adjacent preload pieces to be individually fixed in grip plate upper surface and lower surface;
Preload piece comprises: with the fixing arc-shaped cover of grip plate, be arranged at pretension expansion link and the preloading spring of arc-shaped cover inside;
Grip plate is positioned at arc-shaped cover orthographic projection place-centric and is processed with through hole;
Pretension expansion link is assemblied in grip plate through hole, and two ends stretch out in respectively grip plate; It is arcuation projection that pretension expansion link is inserted into arc-shaped cover inner tip, and the Breadth Maximum of arcuation projection is greater than pretension expansion link diameter, pretension expansion link stretches out in grip plate on-fixed arc-shaped cover end face part end and is provided with block plate, and block plate diameter is greater than through-hole diameter;
Preloading spring is placed on pretension expansion link, and between arcuation projection and grip plate;
Arc-shaped cover both sides have the guide through hole that stretches into and stretch out for cable, and guide through hole be take pretension expansion link central axis as the symmetrical setting of line of symmetry;
Grip plate is processed with cable pilot hole between two preload pieces;
Arc-shaped cover guide through hole place is provided with the guide pipe for cable guiding, mainly facilitates cable to penetrate with the guiding of the inner insertion process of arc-shaped cover;
Arcuation convex surfaces is processed with the limited impression that cross section is semi arch, is mainly used in placing cable and swings at arc-shaped cover the pretension expansion link that comes off;
Adopt the present invention of technique scheme, first cable is led and is penetrated with the arc-shaped cover of first preload piece by guide pipe, continuing to go deep into cable can directly stretch into limited impression and then form a downforce pretension expansion link is pressed down to (preloading spring is subject to force compresses), continue to go deep into cable and by guide pipe connected between preload piece, enter into the arc-shaped cover inside of next preload piece, continue to stretch into cable (second preload piece is the same with first internal compression process), until cable stretches out from the guide pipe of second preload piece other end, then temporary transient positioning cable external part, stretch into again cable, now to be positioned at two preload pieces inner be relaxed state to cable, and then pretension expansion link resets under the effect of preloading spring, cable is carried out to pretension, simultaneously when cable under tension pretension expansion link again pressurized the stretching travel of cable is provided.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
The present invention is totally 2 width accompanying drawings, wherein:
